NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 581,150, dated April 20, 1897.

Application filed March 10, 1896.

To all whom it may concern/.-

Be it known that We, WILLIAM W. DOTY and JAMES J. DONNELLAN, of New York city, in the county and State of New York, have invented anew and Improved Non-Refillable Bottle, of which the followingis a full, clear, and exact description.

The object of the invention is to provide a new and improved non-refillable bottle which is simple and durable in construction and arranged to effectively prevent refilling of a bottle after it is once emptied of its original contents.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of thisspecification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1, and Fig. 3 is a similar View of the same on the line 3 3 of Fig. 1.

The bottle A is provided in its neck B with a conically-shaped opening B, leading at its apex into a valve-seat 13*, formed integrally with the neck, as plainly illustrated in Fig. 1. On this valve-seat B is normally seated by its own gravity an inverted-cup-shaped valve 0, formed at its outer edge with a downwardly-extending flange 0, adapted to engage the inner surface of the neck below an inverted conical chamber B formed in said neck, so that the valve 0 upon openingthat is, when the bottle is tilted-moves with its flange 0 into an enlarged space or chamber to permit the liquid contained in the bottle to flow out through the opening B and around the inner face of the valve and its flange G into the enlarged space B from which the liquid can pass through an annular channel D, formed in a stopper D, preferably made of glass and cemented or otherwise permanently secured in the upper end of the neck of the bottle, as illustrated in Fig. 1. The annular channel D in the stopper D forms a center piece D connected with the outer por- Serial No. 582,537. (No model.)

tion of the stopper by wings D as plainly indicated in Figs. 1 and 2.

Now it will be seen that the annular channel D extends throughout the length of the stopper and has the shape of an inverted cone, with the base-opening at the top of the neck of the bottle, so that the liquid can pass through said channel to the outside. A cap E extends over the upper end of the neck of the bottle and stopper D, and this cap is provided at its under side with a centrally-extending screw E, screwing in a thread D formed in the center piece D of the stopper to permit of moving said cap E close to the upper end of the neck to close the same or a suitable distance away from it to leave the base of the channel D open, as indicated in Fig. 1.

From the screw E extends downwardly and centrally through the center piece D a rod F, having the enlarged portion F, 011 which is secured a ball F engaging the sleeve 0 on the top of the valve 0, said sleeve being surrounded by a cup 0 formed integrally with the valve 0 and on the top thereof, as will be readily understood by reference to the drawings. The enlarged part F serves as a guide for the sleeve 0 of the valve as the latter moves to and from its seat to hold the valve centrally and to permit the liquid to pass the flange O at the time the latter extends in the enlarged space B as. previously explained. Now it will be seen that when the cap E is screwed downward to close the neck of the bottle then the rod F and its ball F is likewise moved downward, so that the ball finally engages the top of the valve O to firmly lock the latter on its seat. By this arrangement the contents of the bottle cannot be spilled, as the neck is securely closed by the valve 0 on the seat B and by the cap E at the upper end of the neck. This arrangement is especially serviceable for shipping bottles, it being understood that the receiver only needs to un-' screw the cap E a short distance, as shown in the drawings, to bring the several parts into a working position.

In the lower portion of the neck, preferably at the under side of the wall of the opening B, are arranged a number of air-pipes Gr, extending throughout the length of the opening to permit air to pass into the bottle at the time the latter is tilted to insure a proper flow of liquid in an outward direction. Similar air-pipes H are arranged in the stopper D in the circular channel D with the inner or lower ends of the pipes formed with an upwardly and outwardly extending bend 11, so that the air can pass into the enlarged space B at the time the bottle is tilted and liquid runs out through the annular channel D. Thus it' will be seen that air for insuring a ready outward flow of the liquid can pass into the bottle by said air-pipes II and G, but when the bottle is in a vertical position, as shown in Fig. 1, then the valve C immediately seats itself on the seat 13*.

It will further be seen that by making the valve cup shape, as described, it is evident that any attempt at refilling the bottle by introducing liquid at the upper end of the channel D causes an immediate seating of the said valve on the seat B so that the liquid cannot pass into the opening B and to the interior of the bottle.

In manufacturing .the bottle the stopper D with the cap E and valve 0 are separate from the neck of the bottle, and when the bottle is filled then the stopper is inserted and eemented or otherwise fastened in place, it being understood that the several parts carried by the stopper then move into proper position, especially the valve 0.

It will be seen by reference to Fig. 1 that the enlarged inner end F of the stem F serves as a stop for the upward movement of the cap E upon unscrewing the latter, as the said enlarged portion abuts with its upper end against the lower end of the center piece D of the stopper.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent 1. A non-refillable bottle, com prising a bottle having its neck provided with a coneshaped opening, a valve-seat at the top of the cone-shaped opening, and an inverted-coneshaped chamber above the valve-seat, and an inverted-cup-shaped valve fitting over the said valve-seat and having its outer edge in contact with the inner surface of the neck when the valve is seated, substantially as described.
